HHHIHHH TE Patented Aug. 18, 1936 RADIATOR Charles T. Bappler, Hartford,Conn, assignor to The Bush Manufacturing Company, Hartford, Conn., acorporation of Connecticut Application September 18, 1935, Serial No.41,156

5 Claims.

My invention relates to the class of devices which are employed forchanging temperatures of fluids, and an object of my invention, amongothers, is to provide a radiator which shall be 5 extremely efiicientand particularly one which may be readily adapted to various conditionsrequiring a variation in sizes without varying the radiating efficiency.

One form of a. radiator embodying my inven- 10 tion and in theconstruction and use of which the objects herein set out, as well asothers, may be attained is illustrated in the accompanying drawing inwhich Figure 1 is an end view of my improved radiator with theconducting tubes in section.

Figure 2 is a view in cross section through the same.

Figure 3 is a top view of a portion of the radiator with a portionbroken out intermediate the ends.

Figure 4 is a side view of the same.

Figure 5 is a view in lengthwise section through a portion of theradiator.

25 Figure 6 is a perspective isometric view of a portion of theradiator.

In the manufacture of radiators of the fin type, to which my inventionis particularly adapted, it is common practice to construct the unitseach to 30 comprise a single tube with a number of fins evenlydistributed along the tube. It is frequently desired to increase thewidth of a structure, consisting of a number of units, withoutinincreasing the radiating surface, and it is also important in suchstructures that the radiating efliciency shall not be impaired. Myinvention has to do particularly with radiators of this type wherein thesize, as to width, may be increased 40 and in which the radiatingsurface is not increased, such a radiator being shown in theaccompanying drawing in which the numeral 1 denotes the conducting tubeof a radiator unit and 8 denotes fins secured to the tube and spaced 45apart along the tube, as by means of spacers 9.

As hereinbefore mentioned it is sometimes desired to increase the sizeof a radiator composed of a number of units, as by spacing the unitsapart widthwise of the structure without varying the radiating functionas by the flow of air currents between the units, and I thereforeprovide means to prevent such currents and to cause all of the aircurrents to pass between the fins.

55 The units |l are spaced apart as shown in Figs. 1 and 2 and are heldin this spaced relation as by means of spacing plates I2 provided atsuitable intervals to rigidly support the structure. These plates arepreferably curved along one edge as at l3 at that portion occurringbetween the units to provide a support for a battle M which is alsopreferably curved and which covers the space between the fins as shownin Figs. 1 and 2.

In a preferred construction an ear i5 is outturned from the edge of thespacing plate I2 and 10 a screw bolt extending through the bafile andear secures the baffle firmly in place.

It will be understood that the baffie is secured to a number of thespacing plates, depending upon the length of the structure, such balileextending for the full length of such structure. It will be furtherunderstood that any number of units l0l I may be employed, as may bedesired, to suit a structure of any size, and the arrangement of theconducting tubes will be such as is common to structures of this type,in each case a baille being employed to cover the space between all ofthe adjacent units.

In accordance with the provisions of the patent statutes I havedescribed the principles of operation of my invention together with thedevice which I now consider to represent the best embodiment thereof;but I desire to have it understood that the device shown is onlyillustrative and that the invention may be carried out by other meansand applied to uses other than those above set out.

I claim:

1. A radiator including a plurality of units each unit comprising a tubewith fins distributed therealong and supported thereby, means forsecuring the units in spaced relation side by side to increase the widthof the radiator, and a baffle located between the edges of the fins toobstruct flow of fluid between the units without changing the influenceof such fiow as to each unit.

2. A radiator including a plurality of units each unit comprising a tubewith fins distributed therealong and supported thereby, means forsecuring the units in spaced relation side by side widthwise of theradiator to increase its width, and a baffle located between the edgesof the fins to obstruct flow of fluid vertically between the unitswithout changing the influence of such flow 50 as to each unit.

3. A radiator including a plurality of units each unit comprising a tubewith fins distributed therealong and supported thereby, spacing platesattached to the units to secure them in spaced 5 cured to saidsupporting plates to cover the space between the units.

5. A radiator including a plurality of spaced units, each unitcomprising a tube with fins distributed therealong, spacing platesattached to the units to hold them in spaced relation, an ear outturnedfrom each spacing plate at one edge thereof, and a baffle attached tosaid ear on each spacing plate and covering the space between the units.7
